Microsoft’s new Lumia phones—the Lumia 950, Lumia 950 XL, and more recently the Lumia 550—have been the subject of speculation for weeks. Now, a leaked presentation that looks very Microsoft-y appears to have put a stamp of authenticity upon the rumors.

Slides posted to Forever Nokia Latin America’s Facebook page (and covered by WindowsStudio) show what appears to be a Microsoft presentation, in Spanish, describing some of the features and specifications of all three new Lumia phones, plus the Continuum dock (known as the Microsoft Display Dock) that they will plug into. In addition, they show that some of the phones will include a version of Windows Hello that will scan your eye’s iris to identify you without a password.

Translated, one slide describes the target consumer of the phone as “everyone who wants to do more; enjoy their daily lives; and share with the people who matter most to them.” That’s casting a pretty wide net for usage cases, with references to productivity as well as social sharing with family and friends.

The new devices use Windows 10, letting them function as your PC, the slides add. The slides don’t use the term ‘Windows 10 Mobile’ specifically.

Why this matters: Windows Phones have captured just a fraction of the smartphone market, but its users are passionate. Given their increasing clamor for new flagship phones, it’s not hard to understand why this information is leaking. Several independent leaks have confirmed similar details, with advertising network AdDuplex confirming the Lumia 550 yesterday. We still don’t know what’s inside the Surface Pro 4, of course. And, most importantly, how it will all work. We’ll have to wait for Oct. 6 to find out.

The three new Lumia phones

If these slides are accurate, here are the specifications of the new phones:

Both phones can be connected to what Microsoft is calling the Microsoft Display Dock, a a small box that appears to have USB and microUSB inputs and connects to an external display. According to the slide, it will also have a Bluetooth connection built-in. The idea, as Microsoft has described previously, is that the two phones will use the Continuum feature to allow them to be used as small PCs, displaying Windows 10 universal apps (like Excel) across the entire screen real estate used by the widescreen monitor.

Yet another slide claims that both the Lumia 950 and 950XL (but not the 550) will employ iris recognition as a means of authentication. Windows Hello on some Windows 10 notebooks uses a special Intel depth camera to scan your face, logging you in without the need to enter a password or PIN. The version of Windows Hello used by Microsoft’s new flagship phones will look for the unique pattern of your iris to do the same. (It’s likely that you’l have to hold the phone fairly close to your eye for this to work, however.)

Both phones have been rumored to work with the Surface Pen that accompanies the Surface tablets, but the slides don’t seem to show that.
